Special Abilities

Acid blood (Ex) The blood of the Xenomorph is highly acidic. Whenever it bleeds, the blood will burn through almost any substance and will cause 3d4+3 points of damage. The blood will continue to burn for 1d6 rounds, causing damage each round. Attacking the Xenomorph with natural weapons is a very poor idea as the target automatically suffers the acid blood damage if they are using slashing or piercing attacks.

Acid Splash (Ex) Whenever the Xenomorph is hit by any type of attack which deals more than 10 points of damage in a single strike; the blood will have a chance to effect anyone near. The acid splash has a radius of 20 ft. and those caught in the area of effect are allowed a Ref save (DC 12) to avoid taking damage. If the save fails, the victim will suffer 3d4+3 points of damage per round, for 1d6 rounds.

Grab (Ex) When the Xenomorph happens to be within range of a hive, it will often attempt to grab and drag a victim back to the hive to be cocooned and impregnated. The creature must make a claw attack, it will do normal damage. If the attack roll successfully hits the target’s KAC +4, the creature automatically grapples the foe as a free action. (If it hits the targets KAC +13, it instead pins the target). If it succeeds, the creature will then drag the victim back to the hive to be used as a host. The victim can attempt to break free while grappled, requiring a successful escape (using the acrobatics skill). If the victim turns out to be ‘troublesome’ the creature can opt to bite in order to make the target more ‘compliant’.

Inner Jaw (Ex) Possessing an additional ‘jaw’ the creature can opt to use this attack. It typically will use this on a grappled target, or it can opt to use this in addition to the bite. The bite does slightly less damage (1d6+8 S) but is more accurate. The creature has a +14 with this particular attack, and if the target is grappled, then the bonus is +17.

Natural Weapons (Ex) Cannot be disarmed.

Spew (Ex) This Xenomorph is able to spew acid in a 30 ft. cone. All targets in the area of effect must make a Ref save (DC 12) or be struck by the acid. The acid will do 3d4+3 points of damage per round for 1d6 rounds. Those who make the save take no damage at all. The beast can use this three times per day.

Stalker (Ex) The Xenomorph is a near-perfect predator. As such it gains a +5 racial bonus to stealth rolls, and whenever the creature is in a hive, this bonus increases to +10

Tail (Ex) Thanks to the longer tail, this creature is able to climb at its full movement rate, and gains a racial bonus of +5 to Athletics.

Vulnerability to fire (Ex) The creature has few vulnerabilities, and fire is one. Whenever it encounters fire, the creature will take an additional 50% damage (rounded to nearest) and suffer a -4 to any saving throws involving fire.


This variant of the Xenomorph is what is produced when a Facehugger is able to implant one of the larger primates which happen to live on most worlds. The creature is stronger and able to withstand more damage than over types, particularly the Drones, and has all the standard aspects of the Xenomorph species.

It has one thing in common with the Spitter Xenomorph – it is able to spew its acidic blood out to 30 feet, and can affect a large number of targets at once.  It thankfully can only use this ability a few times a day; otherwise it would make an already deadly beast even worse!

When it comes to the physiology of the creature, it has the same bio-mechanical build as the other variants, but tends to be more barrel-chested, and the arms are longer (which means it can strike at further ranges). The legs are somewhat shorter, but this doesn’t slow the beast down – in fact, it is quite fast when travelling on all fours.

Like the great-apes they have taken part of their genetic code from, they are physically a lot stronger than their cousins, with the exception of Praetorians, Kings, and Queens. This makes the creatures absolutely terrifying to watch when they being to rip apart metal doors, walls, even men and heavily armored individuals.
